Amphenol Micro-B Series

Main Title

Micro-B series micro bayonet connector

Mixed Media

Amphenol Industrial now offers a lightweight, high performance, small footprint, circular connector series that cost-effectively replaces high-cost connectors used in a variety of industrial markets needing high signal counts in a very small package. The Micro-B series utilizes a robust triple bayonet coupling that provides quick and positive locking, along with an internal EMI ground spring for excellent shell-to-shell conductivity at an affordable price.

This new circular connector series was designed for industrial applications like sensors, data and mobile communications, medical equipment and motor controls where electrical performance must be met with affordability.

The compact, Micro-B features high density insert patterns with size 22D contacts allowing for more circuits to be connected and a simplified termination process with tape and reel contacts. It offers tool-less and fast mating for ease of use in the field.
